I strongly advise you not to fiddle around with files that are so relevant to your OS. They belong to root and are read-only for a reason.

If you want to skip the login-screen (aka Unity-Greeter), go to the "users" aerea of the system settings and edit your account by switching on "automatic login" (may be labelled slightly different, I'm using the German version of 13.04).

Manually editing configuration files is one of the normal ways to adjust settings on most Unix-like systems, including Ubuntu. This problem happens primarily due to a bug.
